This tunnel also lets traffic go both ways, back again from the VPN server to your device, shielding the data inside the tunnel as it goes – and protecting it from anyone lurking just outside. Once the packet arrives at its destination (your VPN server), then this outer layer of data is removed so it can access your data. It works a little bit like putting a letter inside an envelope, meaning no third parties (not even your ISP) can see the data tucked away on the inside. When your device initiates a VPN connection, your entire network traffic passes through a secure tunnel.Īny data sent through the internet via the VPN tunnel is split and encapsulated within “packets” (in essence, another layer of data). Just how secure the VPN connection is boils down to four basic elements, which we’ll go into in more detail on in just a moment: This tunnel opens up at one point (your VPN client) and weaves its way through the internet before emerging at another point (the VPN server). So, think of a VPN connection like a tunnel capable of taking you to a different place on the web. Let’s dig into it together, kicking off with a quick definition of what exactly a VPN tunnel is.Ī VPN tunnel (short for Virtual Private Network tunnel) is a private pathway for data to pass through the internet from your computer or mobile device and another network. What the heck is a VPN tunnel, and how can it help you maintain your digital security and privacy, we hear you ask? And why should you care about how it all works in the first place? (We’ve already waxed lyrical on the benefits of using a VPN before, so we won’t harp on again too much here).Ĭurious to learn exactly how VPNs accomplish this amazing feat in the first place? It’s mainly down to a little-known process called tunneling. In a nutshell, VPNs help you surf the web securely, privately, and with no restrictions. However, there are a number of ways to ward off would-be online snoopers, one of which includes using a Virtual Private Network (VPN). And the internet doesn’t exactly make it hard for your data to be viewed or hacked by others. Whether it’s your Internet Service Provider (ISP) looking to track and sell your data to advertisers, or unscrupulous hackers trying to steal your personal information to sell on the dark web, it sometimes feels like the whole world has a vested interest in snooping on your online activity. It’s just plain creepy to think about, isn’t it?īut the sad fact is, this is just how your connection to the internet works – it’s like an open window into the goings on in your home, and any nosey parker can peep through.
\None of us like anyone and everyone seeing who we are, where we are, or what we’re looking at while we’re online.
